Habitable Zones in Extrasolar Planetary Systems [PDF]

open access: yes, 2002
If we ask the question about the possible existence of the life outside the Earth, we first have to determine the habitable zone (HZ) for our solar system. The HZ of distances between a main sequence star and an Earth-like planet is roughly defined as the range of mean orbital radii which imply moderate planetary surface temperatures suitable for the ...

Biodiversity–food trade‐offs when agricultural land is spared from production

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Biodiversity conservation in agricultural landscapes, the world's predominant land use, could involve sparing, or setting aside, agricultural land from production, implying biodiversity–food trade‐offs. Employing bird species and agricultural data in two panel data sets, we evaluate the extent of set‐aside's trade‐offs in England between 1992 ...

A 3200‐year weathering record of the Mekong River basin by sediments from the South China Sea

open access: yesBoreas, EarlyView.
The Mekong River is a mega‐river in East and Southeast Asia, and precipitation in its watershed influences more than 300 million people. However, the controlling factor in precipitation and weathering in the basin remains controversial. Here we present a high‐resolution record of weathering of the Mekong River basin over the past 3200 years by ...

Opportunities, research gaps, and risks in allogenic ecosystem engineer mimicry

open access: yesConservation Biology, EarlyView.
Abstract In an age of anthropogenically driven species loss and increasingly novel ecosystems, ecosystem engineer restoration is a process‐based approach to supporting ecosystem function. Many ecosystem engineers have low or declining population sizes.

Constraining Background N2 Inventories on Directly Imaged Terrestrial Exoplanets to Rule Out O2 False Positives

open access: yesThe Astronomical Journal, 2023
Direct imaging spectroscopy with future space-based telescopes will constrain terrestrial planet atmospheric composition and potentially detect biosignature gases. One promising indication of life is abundant atmospheric O _2 .

Australian and New Zealand nursing and midwifery educators' planetary health knowledge, views, confidence and teaching practices: A descriptive survey study

open access: yesJournal of Advanced Nursing, EarlyView.
Abstract Aim To explore Australian and New Zealand nursing and midwifery educators' planetary health knowledge, views, confidence and teaching practices. Design A cross‐sectional survey design. Methods An online survey was sent to Australian and New Zealand nursing and midwifery educators across the 45 Schools of Nursing and Midwifery between July and ...

THORIUM ABUNDANCES IN SOLAR TWINS AND ANALOGS: IMPLICATIONS FOR THE HABITABILITY OF EXTRASOLAR PLANETARY SYSTEMS [PDF]

open access: yes, 2015
We present the first investigation of Th abundances in solar twins and analogues to understand the possible range of this radioactive element and its effect on rocky planet interior dynamics and potential habitability.

Confronting the Climate Crisis: Fossil Fuel Hegemony and the Need for Decarbonization, Degrowth, and Democracy

open access: yesJournal of Management Studies, EarlyView.
Abstract In this Counterpoint, we argue for the importance of social movements in responding to the climate crisis by challenging the taken‐for‐granted practices and policies of corporate capitalism. These challenges politicize what is seen as ‘common sense’ and show that there are alternatives to the dominant social order of fossil‐fuelled economic ...

A global network model of abiotic phosphorus cycling on Earth through time

open access: yesScientific Reports, 2022
Phosphorus (P) is a crucial structural component of living systems and central to modern bioenergetics. P cycles through terrestrial geochemical reservoirs via complex physical and chemical processes.

EXPLORING THE HABITABLE ZONE FOR KEPLER PLANETARY CANDIDATES [PDF]

open access: yesThe Astrophysical Journal, 2011
This paper outlines a simple approach to evaluate habitability of terrestrial planets by assuming different types of planetary atmospheres and using corresponding model calculations. Our approach can be applied for current and future candidates provided by the Kepler mission and other searches.
